  • The main use of electrodes is to generate electrical current and pass it through non-metal objects to essentially alter them in several ways. Electrodes are also used to calculate conductivity.
  • The electrode is the location where electron transfer happens. An electrode is classified as either a cathode or an anode counting on the type of chemical response that happens. If an oxidation reaction happens at an electrode.
